Having a IR thermometer is invaluable. One of my cheaper tools and most used. 80 - 82 room temp under an LED is a good guide but can also be misleading. Depends on air circulation/and frequency of exhaust cycles. Sometimes my room is 80 - 82 and leaf temp of 80 which is high. Other times the room is 77 and the leaves are the same. Point is don’t guess at leaf temp. The ideal leaf temp is 75 - 77.

Ye 75-77 I heared is optimol leaf temp

I run my room 80-82f
and leaf temps are reading 79-81ish 82max

But I though my ir gun must be out ,
Because the dibt show any signes of heat stress well not i can tell anyway

Also be iv ordered about 6-9 diffrent make ir guns and usually buy 2-3 if eatch and iv yet to find any thst are accurit, so I give up on leaf temps was driving me mad, i go on room and look again now, also opening a small tent the leaf temps can often shoot down quick
